No, Not at all , The search engine will bring traffic to you site. but it is in your hands to convert it in to a sale, Otherwise you are unnecessarily wasting your band width.
well , if you don't have good , original content on your site you wont have any traffic from the search engine . you may optimize your site as much as you want . content plays an important role in success .
yes you are true content is the king of a website. it grabs new visitors + repeated type in traffic visits which is available with out the help of search engine
I agree. It is good that people find your site but it is better if they like it, if they find it relevant to whatever they were searching for in the first place. Like Eukristian said, content plays an important role in the success of any e-business.
This will maybe be a little off topic but what do you guys think is it worth creating a site in html on which there is a need to add content like you said to attract people to site, or html should only be created for company information and something like that?
